Why Is My Energy Bill So High? Here’s Why and How To Lower It

Updated on February 28, 2025

If your energy bill keeps climbing, you’re not alone. Many Ontario, CA homeowners experience unexpected spikes in electricity costs, especially during extreme temperatures. But what’s causing your bill to soar – and how can you lower it?

At Macawsome Heating & Cooling, we help homeowners identify hidden energy drains and improve efficiency. Let’s break down why your energy bill is high and what you can do about it.

How Ontario’s Climate Affects Your Energy Bill

Ontario’s hot, dry summers and mild winters play a major role in energy consumption. DUring summer, air conditioners work overtime to combat triple-digit temperatures, leading to higher electricity usage.

While winters are milder, heating systems are still in use, contributing to seasonal spikes in utility costs. The more extreme the weather, the harder your HVAC system works – and the higher your energy bills climb.

Common Reasons for High Energy Bills

If you’re asking, “Why is my energy bill so high?”, the answer likely lies in your home’s energy efficiency. Several factors can cause excessive energy use, including:

Poor Insulation

Gaps in insulation let heat in during summer and escape in winter, forcing your HVAC system to work harder to maintain comfortable temperatures.

Inefficient HVAC System

An old, dirty, or poorly maintained HVAC system consumes more energy to regulate temperatures. If your system hasn’t been serviced recently, it may be driving up your electricity costs.

Phantom Loads

Even when turned off, some devices continue to drain electricity – a phenomenon known as phantom loads. TVs, gaming consoles, and chargers plugged in all day add to your bill without you realizing it.

Appliance Overuse

Frequent use of high-energy appliances like ovens, dryers, and dishwashers – especially during peak hours – can lead to unnecessary energy waste.

Window & Door Drafts

Leaks around windows and doors allow conditioned air to escape, making your HVAC system run longer and use more energy.

How Your Home Habits Impact Your Energy Bill

Beyond your home’s efficiency, your daily habits could be wasting energy without you realizing it:

  • Leaving electronics plugged in draws power even when they’re not in use. Unplugging devices reduces unnecessary electricity usage.
  • Skipping HVAC maintenance leads to higher energy consumption. A well-maintained system runs more efficiently and uses less power.
  • Running appliances during peak hours (when electricity demand is highest) results in higher rates. Shifting usage to off-peak hours can help cut costs.

How to Lower Your Energy Bill

Want to reduce your electricity costs? Here are the best strategies for lowering your bill without sacrificing comfort:

  1. Upgrade Your Insulation: Better insulation stabilizes indoor temperatures and reduces strain on your HVAC system. Less energy wasted = lower bills.
  2. Maintain Your HVAC System: Schedule regular tune-ups to ensure your heating and cooling system runs efficiently and consumes less electricity.
  3. Unplug Unused Electronics: Eliminate phantom energy loads by unplugging devices that aren’t in use or using a smart power strip to cut off standby power.
  4. Switch to Energy-Efficient Appliances: Replacing old appliances with ENERGY STAR-rated models can lead to long-term energy savings.
  5. Seal Windows & Doors: Proper sealing prevents air leaks, helping your home maintain a consistent temperature with less energy.
  6. Use LED Lighting: LED bulbs consume up to 75% less energy and last significantly longer than incandescent bulbs.
  7. Take Advantage of Off-Peak Hours: Running large appliances outside of peak demand times can lower your utility costs, depending on your provider’s pricing structure.
